If the angles are of equal measure, then the measure of the angles be x and x respectively.
Then,
x+x=180
⇒ 2x=180
⇒ x=90

Let x be the angle.
Given, supplement of angle x is 65o
=> x+65o=180o
x=115o
But the complement of the angle 115o degrees cannot be determined. Because of the pair of angles whose sum is 90° is called complementary angles.

Linear pair of angles must add upto 180°.
If one of the angle forming a linear pair is right angle (90°).
The other angle would obviously be 90°.
As it would add upto 180.

(i) No. Acute angle is always lesser than 90º. It can be observed that two angles, even of 89º, cannot add up to 180º. Therefore, two acute angles cannot be in a supplementary angle pair.

Let the x be the measure of the two angles which are supplementary.
x+x=180o
2x=180o
x=90o
∴ measure of an each angle = 90o

The sum of the measures of two supplementary angles is 180°.
Let the measuare of angle is x
x + 135° = 180°
x = 180° - 135°
x = 45°
∴ The measure of the supplement of an angle of 135° is 45°.

Let us have a detailed look at the different parts of the respiratory system and their functions.
Nose
The nose possesses a couple of exterior nostrils, which are divided by a framework of cartilaginous structure termed as the septum. This is the structure that evenly separates the right nostril from the left nostril. Tiny hair follicles that cover the interior lining of nostrils acts as the body’s first line of defence against foreign <a href="https://byjus.com/biology/pathogen/">pathogens</a>. Furthermore, they provide additional humidity for inhaled air.
Larynx
Two cartilaginous chords lay the framework for the larynx. They are situated at the point of joining the pharynx and trachea. It is also termed as Adam’s apple or the voice box. It is the portion which rises and falls during swallowing of food particles. It generates sound as air passes through the hollow in the middle.
Pharynx
The nasal chambers open up into a wide hollow space termed as the pharynx. It is a common path for both air and food. It functions by preventing the entry of food particles into the windpipe. The epiglottis is an elastic cartilage, which serves as a switch between the larynx and the oesophagus by allowing the passage of air into the airway to the lungs, and food in the <a href="https://byjus.com/biology/gastrointestinal-tract/">gastrointestinal tract</a>.
Have you ever wondered why we cough when we eat or swallow?
Talking while we eat or swallow results in incessant coughing. The reason behind this reaction is the epiglottis. It is forced to open for the air to exit outwards and the food to enter into the windpipe, triggering a cough.
Trachea
The trachea or the windpipe rises below the larynx and moves down to the neck. The walls of trachea comprise C-shaped cartilaginous rings which give hardness to the trachea and maintain it by completely expanding. The trachea extends further down into the breastbone and splits into two bronchi, one for each lung.
Bronchi
The trachea splits into two tubes termed as bronchi, which enter each lung individually. The bronchi divide into secondary, tertiary, and to bronchioles, which is again further divided into small air-sacs called the alveoli. The alveoli are minute sacs of air with thin walls and single-celled manner. It enables the exchange of oxygen and carbon dioxide molecules into or away from the bloodstream.
Lungs
Lungs are the chief centres of the respiration in humans and other vertebrates. They are located in the thoracic cavity of the chest near the backbone and on either side of the heart. They are the pair of large, spongy organs, mainly involved in the exchange of gases between the blood and the air. Compared to the left lung, the right lung is quite bigger and heavier.

Let x% of 125=10
So,
125× x/100 =10
₹125x=10×100
x= 10×100/125
x= 10×4/5
x=2×4=8%

In ΔABE and ΔACF,
∠BAE=∠CAF (Common angle)
∠AEB=∠AFC ....(∵BE⊥AC and CF⊥AB)
BE=CF (Given that altitudes are equal)
By AAS criterion of congruence,
ΔABE≅ΔACF
Hence,
AB=AC (by CPCT)

since , AB is a line segment,
L is drawn perpendicular to AB,
A point 'p' lies on line L.
( as shown in the diagram in the attachment )
To prove : P is equidistant from A and B.
Prove :- In ∆AOP and ∆BOP ,
OP = OP ( common side )
POA =
POB
AO = OB
∆AOP
∆BOP (By S.A.S.)
=> AP = BP ( By C.P.C.T. )
Hence , "P" is equidistant from A and B .

An altitude of a triangle is a line segment that starts from the vertex and meets the opposite side at right angles.
A median of a triangle is a line segment that joins a vertex to the mid-point of the side that is opposite to that vertex.
